Register FILEVISTACONTROL

I used the second example for FileVistaControl, and I got everything to work fine. Now I don't know how to register for the software. It's very clear for the first example but how do you register for the second example, in the code behind??

Thanks

Issue has been solved

I haven't got any email from you, probably at work they're filtering the emails but I should be getting responses in dev_.net@hotmail.com.
Anyway everything works fine and your software is great you saved my deadline!!!
Cheers!! 
Thanks a lot
Juan
